With the introduction of advisory coder reviews, coder will run after every simpletest run. As a result, the 'most recent log' displayed on the admin/pifr page will almost always be a coder run, and the associated simpletest run ends up hidden/unavailable.

It would be nice to store the log files for the last x runs, so that one could debug the results from all environments associated with a single test from directly on the testbot instead of having to head over to qa.d.o.
